Abstract

A valve arrangement has a housing in which are arranged an electromagnetically actuatable pilot valve controlling a differential pressure and a main valve actuatable by the differential pressure, the closure member of the main valve permitting a connection to be established between an outlet port and, alternatively, a first or a second inlet port. In order to keep the overall length of the valve arrangement as small as possible, the present invention provides a joint axis (29) of the pilot valve (5) and of the electromagnet (6) actuating the pilot valve (5) which is perpendicular to the axis (30) of the main valve (7) in a plane that is radially offset relative to the axis (30). In the inactive position, both compartments (23, 24) are exposed to the higher pneumatic pressure.
